CFrame rotation to Mouse Position?

It's probally really simple but I'm making a tank turret rotate to the mouse position.

I have this piece of code here.

Mouse.Move:connect(function()
	MouseX = Vector3.new(Mouse.Hit.x,0,Mouse.Hit.z)
	Turret.TurretWeldToHull.C0 = CFrame.new(Turret.Position,MouseX):inverse() * CFrame.new(Turret.TurretWeldToHull.Part0.Position.x, Turret.TurretWeldToHull.Part0.Position.y - 7,Turret.TurretWeldToHull.Part0.Position.z)
end)

But I have two problems.

I. The turret starts doing weird stuff whenever the mouse comes near it. I'm trying to spin the turret in one axis.

II. The turret is facing the wrong way! How can I fix that?

Thank you!

It's currently set to follow the mouse's 3D position, as if the mouse was always on the ground; this explains why the turret is also looking towards the ground (especially as the mouse gets closer to the turret).

MouseX's Y coordinate should be at the exact same height as the Turret (or possibly Turret - 7, to be consistent with the second CFrame on line 3).
